Which article focuses on the identification and use of grounded conductors?

The focus of Article 200 in the National Electrical Code (NEC) is on the identification and use of grounded conductors. This article outlines the requirements for properly marking grounded conductors to ensure safe and effective electrical installations. Grounded conductors, often referred to as neutral conductors, play a critical role in electrical systems by providing a return path for current and reducing the risk of electric shock.

Article 200 specifies how to identify these conductors by requiring unique color coding or marking. For instance, it states that grounded conductors generally must be identified by a white or grey insulation color, ensuring that they are easily distinguishable from ungrounded conductors. This helps in maintaining safety and consistency across electrical installations.

Understanding the principles outlined in Article 200 is essential for electricians, as it ensures compliance with safety standards, minimizes the risk of errors in wiring, and supports overall electrical system integrity. Proper identification of grounded conductors is crucial for both installation and maintenance, ensuring that all electrical work is performed safely and in line with code requirements.
